Altitude Sickness on Kilimanjaro: Prevention & Tips

At altitude there is less oxygen in every breath, and the body needs time to adapt. Most climbers feel at least mild symptoms — understanding them is the key to a safe summit.

Common symptoms of mild AMS

Acute Mountain Sickness (AMS) can cause headaches, light-headedness, nausea, loss of appetite, tingling fingers and toes, and disturbed sleep. Mild symptoms usually pass within 24–48 hours and are not dangerous — but they should always be reported to your guide.

How we keep you safe

• Routes and itineraries built around "climb high, sleep low"
• Daily health checks — pulse, oxygen saturation and symptom reviews
• Emergency oxygen and first-aid equipment on every climb
• Helicopter evacuation coordination with Kilimanjaro SAR when needed

How you can help yourself

• Go slowly — pole pole is the phrase of the day
• Drink 3–4 litres of water daily
• Avoid alcohol, tobacco and sleeping pills
• "Don't go up until symptoms go down" — communicate openly with your guides

Some climbers use Diamox (acetazolamide) to aid acclimatisation — always consult your doctor first and tell your guide what you are taking. See our Search & Rescue page for evacuation and insurance details.
